T (ZZZ/whom it may concern Be it known that l, biononor; 'Wimz, acitizen oi? the United States, and re ident of 5, Flg. 4.;

Rochester, in the county oi Monroe and 5 State of Yew Yorlnhave inventedcertain new and useful Improvements in Slicing Machines, of which thefollowing is a specification.

The. present invention relates to' slicing machines and an objectthereoi is to provide an improved means tor feeding toward the cutter atable or carriage on which the material to be sliced lSllBlCl. Anotherobject of the invention is to provide means for pro-- venting any hacklush in the carriage which su p mrts the materialtohe sliced so that thepressure of the cutter upon the material on the carriage will not shiftthe carriage and produce uneven slices. A further object of theinvention isto provide in connection with a mechanism for feeding thecarriage toward the cutter step by step, a friction clutch which willhold the carriage in its shifted position so that it will not. he movedbackwardlyby pressure'on the material during the cuttingaction. Stillanother ohiect of the inventionis to provide a-means-bv which thecarriage on which the mat rial to be sliced is arranged may betreed inthe feeding or shitting mechanism and also from a back lash clutch topermit such carriiug e to be shifted away lrointlie cutter. A stillfurther object of the invention is to provide an improved mechanism forfeeding the carriage in the direction of the plane of operation of therotary cutter and driven. with said mechanism. further object ot' theinvention is to provide an improved means for securing the guardfor therotary cutter in operative position.

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinatter described, thenovel features being pointed out in the appended claims.

In the illustrated embodiment of thej'invention, ther'eha's beenprovided a base 1 from which rise two uprights 2 and 3 con nected by anintermediate cross member 4. Connecting the uprights 2 and 3 above thecross piece 4 is a shaft 5 on which a dish or circular cutter 6 issecured as by nalled in the cross piece 4., said shaft 10; also having acrown gear 11 secured tlieretoQand meshing with a bevelled gear 12 on anppin joi irnalled on the cross piece -lendfin the upright piece 2 andhaving a crank handle 14 thereon through which movement of the rotarycutter 6 is effected. Operable on the frame and particularly, in thisinstance, on the side frames 2 and 3 in the line a, nut 7. i This shaftis provided with a bevelled pmion 8 which meshes with a crown gear 9,

a direction substantially parallel with the plane of operation of thedisk or rotary cut ter 6 is a carriage '15. In order to guide thiscarriage, the guiding surfaces 16 and 17 are provided, respectively, Ion the side trams pieces 2 and 3. The guide surface 16 is overhung by aprojection 18'wliich"cooperates with the upper surface otthecarriage,while the guiding surface}? is overhung by a projecting rib 19 whichentends into a groove or recess 20 formed n the side ot a dependingprojection 21 on the,

under sideof the carriage I The opposite side of this dependingprojection :2lis engaged by a removable retaining strip'22 securedto theside piece 3 byscrews 23. I

Movement, of thejcarriage 15 may beef- ,fected in any suitable mannerbut it is preterred to operate the same so that each retation of thecrank shaft 13 will effect a complete back and forth movement oi? thecarriage 15. This result, in' this instance, obtained by providing alever 24 pivoted at to the upright 2 and at 25 to one end of a link 27which in turn is pivoted at 28 to the under sideol the carriage 15. Thelink 24 has pivoted thereto at 29 a link or pit man 30 which in turn ispivoted at 31 at an eccentric pointon the crown gear 9, so that motionis transmitted. from said crown gear, in the rotation of the latter, tothe le and from the latter by way of inn. the carriage 15.

The carriage 15 also acts as a support for a carriage in this instance,in the form of a plate or table guided by guide strips and 34 on thecarriage 15 at a right angle to the line of n'iovement of said carriage15, so that the carriage 32 moves on the carriage 15 on a linesubstantially at a right angle to the plane ot' operation of the rotarycutter 6. v

The movement of the carriage 32 may be effected in any suitable manner.In this instance, the carriage 32 has on its under side a tooth or rackbar 35 with which a pawl 36 is adapted to engage through a tooth 37,this pawl 36 being pivoted at 38 to one arm of a swinging or bell crankmember 39 which in turn is pivoted at 40 to the carriage 15. A spring 41acts between the swinging member 39 and the pawl 36 to maintain thetooth 37 toward the tooth bar 35. Tothe swinging mem her or hell cranklever 39, a link 42'is pivotedat 43, this link also being pivoted at 44to an adjustable lever 45 which is pivoted at 46 to the carriage 15. A.spring 4'? connects the link 42 with the swinging member 39 and tends tohold the adjustable lever 4.5,link 42 and swinging member 39 so that thepawl will lie in cooperation. with the tooth bar 35. The lever 45 has anextension or arm 48 at one side oi: the carriage 15 to cooperate with aside taco 2 the 'i'ranie piece 2 just prior to the carriage 15 reachingone end of its movement. When this projecting arm 48 cooperates with theframe piece 2, which forms a stop or abut ment, the adjustable lever 45is shifted on its pivot 46 and the link 42 pulls the swing ing member 39against the action of the spring 47 to shift the pivot 38 or" the pawl36 so that the tooth v37 oi said pawl will, by engagement with the toothbar 35, feed the carriage 32 a predetermined distance. When the carriage15 begins its return movement, the spring 47, in returning the arnr43 toits normal position, will act on the swinging member 39 in the directionto shift the resilientlyheld pawl 36s0 thatthe tooth 37 will ride overthe tooth bar 35..

The amount of the feeding of the carriage 32 may be determined by anysuitable means. In this instance, there is provided an adjusting screw49 which is mounted on the adjustable lever 45 and is adapted-to covoperate with a fixed stop or abutment 50 on the under side of the tableor carriage 15. By adjusting this screw the movement of the adjustablelever 45 after engagement with the face 2 of the frame piece 2 may bevaried, as the position of the arm 48 with reference to the carriage 15is changed. There may also be employed, in connection with the feedingmechanismfor the carriage 32, an indicating means, which, in thisinstance, is in the form of a pointer 51 on the lever 45 operating in aslot 52 in the carriage to cooperate with, the scale or indications 53on the top surface ot the carriage 15 adjacent the slot it is alsopreferred to employ in eonnection with the carriage32 a clutch or otherback lash device which will prevent even the smallest amount of movementof the carriage 32 away from the cutter after each Feeding action. Inthis instance, this clutch is in the term of a cam surface 54 on amember pivoted at 55 on the carriage 15,'the cam surface 54 beingadapted to cooperate with the carriage 32 to prevent the return of thelatter while, at the same time, permitting the feeding of said carriage32 to,-

ward the cutter. cam member 54 to maintain it in cooperation with thecarriage 32 while, at the same time, permitting the yielding of said cammember when the carriage 32 is fed toward the cutter. g

Vfith the end in view of permit-ting the carriage 32 to be moved awayfrom the cutter, a controlling rod 57 is employed, this red having afinger piece 58 through which it may be pulled and liaviiiur also apivotal connection at 59 with the pawl 36 so that the latter may bedisengaged from the rack bar 35 to permit the carriage being shifted byhand toward its starting position. In orderto control also the clutch orcam member 54, the rod 57 has connection through an arm 60 on saidclutch member and a shoulder 61 on the rod through which the clutchmember 54 is shifted out of engagement with the carriage 32 when the rod57 is pulled to release the carriage t'rom'the pawl 36.

With the end in view of protecting the user of the machine against therotary cutter 6, the latter may be provided witha guard 62 in the formof a segment of a ring which provides a space between its ends throughwhich the knife may be engaged by the material on. the carriage 32. Thisring segment is L shaped in a cross section so that it will cover theedge of the knife as well as the front face of said knife adjacent'theedge. In this instance, this guard is pivoted on a A spring 56 acts onthis frame when the first mentionec That I claim as my invention anddcr-lirc.
